Card Set Information
all living things
made advancements in the 19th century in microbiology
was the first to observe microscopic life (blood, plaque, algae)
know as T.B.
know as Bacteriology
know as phcology
know as protosology
know as virology
-cell type is simple
Bacterias cell size:
Bacteria is considered?
human (organic molecules)
Bacteria, effects what in the Ecosystem:
-some cause diseases (ecoli, saminalia, strep, tetnius)
-very few cause diseases
nitrogen fixing bacteria
this is when living organisms metabloize
ex. (dead animal on the road decomposing gives back carbon dioxide in the air and nutirents to the animals and plants.
corn, the other carbohydrate
-single cell (unicellular)
Alage cell size:
it can with stand very cold and very hot tempeatures
-primary producer of organic molecules
what is the by product of photosynthesis?
Few alage produce toxins:
Ex. the "red tide"...harmful alage that bloomed in the Gulf of Mexico and made the water appear red from the microorganisms.
(unicellular) yeast and (multicellular) molds,mildows and molds)
Fungi's cell size:
a few to 100 microns
only orgnic matter
decomposing of any naturally occuring organic molecules.
non living organisms can breakdown this stuff
unicellular and colonies (protozon, alage)
cell wall photosynthetic and atrophic
cell wall, made of (chitin)
lacks a cell wall, hetero, eukaryotic, mulitcellular (only in amimals)
live in harsh enviorments
man and animal
Cell Structure and Functions...
Prokaryotic vs. Eukaryotic
-not complex, no nucleus, and no mitocchondria
(plants, animals, fungi, and protozoans)
(cellulose and chitin)
-bi-layer of phospholipids and protein molecules
-very flexible, selectively permeable
very thick and riged, the riged body determins the cells shape
-the cell wall provides protection
(from loss or gain of water)
1/1,000,000 of a micron
antibodies, foods such as mushrooms and cheese do what?
produce useful products
-unicellular (some colinies)
live in water, soil, and on the bodies of other life forms.
what are the 3 types of
Protozoans cell size:
effects of protozoans:
they cause decomposition and pathogyn's
-one benifts form the other and on one is affected
both species benefit, one doesnt effect the other.
human and mosquitoes
not all are cellular (parasite)
- no independent immune system
-they are obligated, intrcellular parasites of hosts cells
cell size of a virus:
they are 1/1,000 of a micron and are harmful
the habitat of a virus:
all living organisms
the effects of the virus:
it kills the host of the cell
few bateria are without a cell wall, in bateria the shape will be off.
are bacteria that naturally lack a cell wall
naturally arise form mutaiton in the wall forming genes.
-they also can be induced artifically by treatments.
what the L-Forms do?
breaks down cell wall material of certain bacteria
-some bacteria have posionous cell wall material
-is a capsule or silver layer
-slimy secretion of cell membrane
-located ext. to the cell wall
the thickness of Glycocalyx:
it varies on the enviormental conditions
(98%, H2O and 2% polysacch or polypeptide)
Strptococcus pneumonia is caused by:
Streptococcus pneumonia has __ strains?
75 different strains
milk kills bacteria and pathogens which the bacteria causes the milk to become "ropy"
the glue of life
ex. (build up on the toliet bowl, or shower, algae on the sides of the swiming pool and plaque on your teeth)
eukaryotic cell "true nucleus" 3-700x more that bacteria.
Chromosome shapes are:
mass of DNA molecules/"naked DNA"
during___the___is arranged into multiple chromosomes (liner)
what are the 3 types of plasmid transfer:
needs (pili) to attatch species and the formation of a bridge to transport DNA
eats the host, (hazard) not as controlled
Ex. of new phenotype:
"recombinant bacteria": (recombination of genetic material)
-antibiotic resistant strains of bacteria
-species which produce useful products/service.
what is signficant about ribosomes:
function is proteinsynthys, site of protein molecules
prok. cells have to have___they are smaller in___than ____:
ribosomes, prok, euk.
cytoplasmic inclusions & vacuolos:
they are visable with a light microscope & organic matter..."food"
source of Nitrogen
make things float
botulism (food posining)
